Seriously, who would have thought.

It's not that hard to believe these flying things being hit by the blades whose tips move at about 200 MPH.

I think the effect would be like a speeding car that keeps honking it horn. You can't hear the horn till it's to late.

Regarding the latest news, it remains to be seen what the Royal Society for the Protection of Bats' position is on this matter.

Denmark studies this in 2001 (there are hundreds of giant windmills in that tiny country):
Windmills: 30,000
Automobies: 1,000,000
Cats: 55,000,000

If it were up to me, we could ban cats, instead!

I hope you get along well with mice.

Plus there are far fewer raptors than sparrows.
It isn't enough to simply post the numbers.

I believe there is paper work also with each one.
This is a simular issue with power lines.
So why can't we just help nature replace the lost raptors? Or even bats?
We do it with fish, and endangered species.

RE: How wind trubines kill bats
I am very happy with the return of red kites (some sheep farmers not so happy) to parts of Wales. Never mind wind turbines, their survival has been difficult as they are vulnerable to unhappy farmers shooting or poisoning even now they are protected. When populations are at risk, just a few extra mortalities can trip the population over the edge.
Unliek song-bird or scavenger populations, raptor populations are much smaller as might be expected and thus more vulnerable.

RE: How wind trubines kill bats
Yes reducing the number of bat or raptor deaths is desirable, but as I pointed out there are alternitives to keep the species viable.
If you consiter the life time length of the wind turban, probally about 15 years, which is short in natures scheme. So we only need to worry about it for this cause for this time period.
However, the question remains, what will happen to the wind farms after there life? Will they be abandon, destroyed, or life extended?
So how long will be required to sustain these species?

RE: How wind trubines kill bats
Thanks for your comments. I read the doubt and humour mixed together.
BI: It appears to be standard practice amongst those types of studies to normalize death rates attributable to one particular factor with all other known factors.
JMW: It isn't enough to simply post the numbers.
Good points, but what alternative do you propose? Of course they seem exaggerated! I'm not a wildlife zoologist, so I'm not well equipped to think critically about studies of bird populations, migration routes, death rates, predators, differential vulnerabilities between species, etc... but what choice do I have? I agree that every time someone with a vested interest produces a "study", the public is stuck either evaluating the results or accepting them wholesale.
My personal approach is to repeat these figures, with references, on a forum where there is a chance for some reasoned debate and see which way the wind blows.

So, now we need to maintain the population of an invasive species we tried to eliminate for the sake of an industry that would not have existed had the invasion never happened.
